To study the resource productivity and efficiency in different vegetables, Cobb-Douglas type of production function was fitted. Two firms operating vegetable supply chains in Bengaluru rural district of Karnataka were identified, they were HOPCOMS (Cooperative) and Reliance fresh (Corporate). A sample of 180 farmers was selected using random sampling method and data was collected through personal interview method. Among the different vegetable supply chains major vegetables cultivated were identified by conducting a pilot survey in the study area, two major vegetables viz., tomato and beans were selected for the study based on maximum production and major vegetables procured. The results revealed that, the production function analysis for tomato, the elasticity coefficient for human labour and fertilizer in Reliance fresh, FYM and fertilizer in HOPCOMS, FYM, fertilizer and plant protection chemicals in traditional marketing channel were negative and the production function analysis for beans, the elasticity coefficient for FYM and fertilizer in Reliance fresh, human labour seed and FYM in HOPCOMS, FYM, fertilizer and plant protection chemicals in traditional marketing channel were negative, indicating over utilization of these resource. Efforts should be made through Raitha Samparka and Krishi Vigyana Kendr as to utilize farm resources rationally and to enhance productivity and profitability. | Resource use efficiency of major vegetables in different supply chains in eastern dry zone of Karnataka, India
